While Colbert was thankful for the initial tweet, he was not pleased with the Trump tweet that followed shortly after. The president tweeted, “Study what General Pershing of the United States did to terrorists when caught. There was no more Radical Islamic Terror for 35 years!”

Trump was referring to an alleged incident in which Pershing executed 49 Muslim POWs during the Philippine-American War using bullets dipped in pig’s blood. Trump alleges the general let one Muslim prisoner go so that he could tell others, resulting in years of peace.

Colbert pointed out that this story has been widely disproven by historians, though the late-night host did share a Pershing quote that reminded him of Trump. The quote was: “A competent leader can get efficient service from poor troops, while, on the contrary, an incapable leader can demoralize the best of troops.”
